THEORY:

The controlled rectifier converts AC voltage to a DC voltage in a controlled manner.

The modeling of this converter is an important step in the designing of a controller for the

closed loop control system typically found in electrical drives. In controlled rectifier, the

output DC voltage is controlled by controlling the delay angles (or firing angles) of the SCRs

used in the converter. The relation between the average voltage Va, and the delay angle (or

firing angle) of a single-phase controlled rectifier is given by

Where,

- is the delay angle.

Vm - is the peak input voltage and

Va - is the average output voltage.

It describes the average behavior of the rectifier over a period of the output voltage.

For a given delay angle, the instantaneous output voltage will contain low frequency ripple at

the multiples of the input voltage Frequency (100Hz and 300Hz for a single and three phase

rectifier with 50Hz supply frequency). If the load inductance is low, this low frequency ripple

will be reflected in the output current and in the torque of the DC motor. This circuit uses

SimPowerSystems. It models a two-quadrant three-phase rectifier drive for a 200 HP DC

motor.

THEORY:

Chopper is a static device that converts fixed DC input voltage to a variable dc output

voltage directly. A chopper is a high speed on/off semiconductor switch which connects

source to load and disconnects the load from source at a fast speed. Choppers are used to get

variable dc voltage from a dc source of fixed voltage. Self commutated devices such as

MOSFETs, Power transistors, IGBTs, GTOs and IGCTs are used for building choppers

because they can be commutated by a low power control signal and do not need

communication circuit and can be operated at a higher frequency for the same rating.

Chopper circuits are used to control both separately excited and Series DC Motors.
